From: Takashi Iwai <tiwai(a)suse.de> [ Upstream commit 67d64069bc0867e52e73a1e255b17462005ca9b4 ] Use the new quirk bits to manage the generic implicit fb quirk entries.

[PATCH AUTOSEL 5.18 16/49] ALSA: usb-audio: Add quirk bits for enabling/disabling generic implicit fb

From: Takashi Iwai <tiwai(a)suse.de> [ Upstream commit 0f1f7a6661394fe4a53db254c346d6aa2dd64397 ] For making easier to test, add the new quirk_flags bits 17 and 18 to enable and disable the generic implicit feedback mode.

[PATCH AUTOSEL 5.18 06/49] ASoC: amd: Add driver data to acp6x machine driver

From: Mario Limonciello <mario.limonciello(a)amd.com> [ Upstream commit e521f087780d07731e8c950f2f34d08358c86bc9 ] Currently all of the quirked systems use the same card and so the DMI quirk list doesn't contain driver data. Add driver data to these quirks and then check the data was present or not. This will allow potentially setting quirks for systems with faulty firmware that claims to have a DMIC but doesn't really.

[PATCH 0/5] seq: add interface for queue timer
by GitHub pull_request - opened 01 Jun '22

01 Jun '22

alsa-project/alsa-gobject pull request #72 was opened from takaswie: Current implementation uses function of QueueTimer to retrieve data for variants of queue timer, however it's not enough convenient in the case of language bindings. The usage of GObject.Value in object property is expected to be supported widely instead. This patchset uses object classes derived from GObject to express the variants. The common properties are expressed by QueueTimerCommon interface. The ALSATimer variant is currently supported to implement the interface. ``` Takashi Sakamoto (5): doc: seq: fix URL to document for ALSATimer seq: queue-timer-common: add common interface for queue timer seq: queue-timer-alsa: add class for queue timer specialized to ALSA Timer seq: user-client: use QueueTimerCommon interface instead of QueueTimer seq: queue-timer/queue-timer-data-alsa: remove unused gobject classes doc/seq/alsaseq.toml.in | 2 +- doc/seq/urlmap.js | 2 +- src/seq/alsaseq.h | 5 +- src/seq/alsaseq.map | 16 +- src/seq/meson.build | 8 +- src/seq/privates.h | 21 ++- src/seq/queue-timer-alsa.c | 134 +++++++++++++++++ src/seq/queue-timer-alsa.h | 22 +++ src/seq/queue-timer-common.c | 87 +++++++++++ src/seq/queue-timer-common.h | 20 +++ src/seq/queue-timer-data-alsa.c | 76 ---------- src/seq/queue-timer-data-alsa.h | 32 ---- src/seq/queue-timer.c | 138 ------------------ src/seq/queue-timer.h | 26 ---- src/seq/user-client.c | 42 +++--- src/seq/user-client.h | 4 +- ...q-queue-timer => alsaseq-queue-timer-alsa} | 8 +- tests/meson.build | 2 +- 18 files changed, 325 insertions(+), 320 deletions(-) create mode 100644 src/seq/queue-timer-alsa.c create mode 100644 src/seq/queue-timer-alsa.h create mode 100644 src/seq/queue-timer-common.c create mode 100644 src/seq/queue-timer-common.h delete mode 100644 src/seq/queue-timer-data-alsa.c delete mode 100644 src/seq/queue-timer-data-alsa.h delete mode 100644 src/seq/queue-timer.c delete mode 100644 src/seq/queue-timer.h rename tests/{alsaseq-queue-timer => alsaseq-queue-timer-alsa} (76%) ``` Request URL : https://github.com/alsa-project/alsa-gobject/pull/72 Patch URL : https://github.com/alsa-project/alsa-gobject/pull/72.patch Repository URL: https://github.com/alsa-project/alsa-gobject
